Rain! I hope the basement isn't flooded.
This graphic shows one-hour precipitation totals from 2 to 3pm as integrated by the Lincoln IL NWS radar installation. A very wet upper air disturbance passed through here today, but must have interacted with some other feature in the atmosphere, because it kept reforming near here and by the time it all moved on, had dumped more than two inches of rain just north of here. We seem to have escaped the very worst, but it was still an awful lot of rain in a very short amount of time.
